SEAL-LOCK.

SPECIFICATION forming part Of Letters Patent N0. 561,347, dated dune 2,1896. Application filed February 21,1896- $erial No. 580,207. (Nomodel.)

To all whom it may concern:

Be it known that LWILLIAM S. Sonnonnnn, a citizen of the United States,residing at Ohicago, Cook county,Illinois, have invented certain new anduseful Improvements in Seal- Locks, of which the following is aspecification.

The object of my invention is to provide a simple, economical, andeflicient seal-lock for freight-car doors; and the invention consists ofthe features and combinationshereinafter described and claimed.

In the accompanying drawings, Figure 1 represents a front elevation ofmy improvement shown in connection with a portion of a car door andframe; Fig. 2, afront elevation of the body portion of the seal; Fig. 3,a rear elevation of the same; Fig. 4, a plan view of the body portion,looking at it from the top; Fig. 5, a front elevation of thesealing-pin, and Fig. 6 a side elevation of the sealing-pin.

In the art to which this invention relates it is well known that thesealing-pin is usually attached to the car-door frame by means of achain or cable. This is objectionable in that it renders it easy forpersons to detach the pin and take it away for uses other than those forwhich it was originally intended. As a consequence many thousands ofpins are lost annually, resulting not only in the loss of the article,but in leaving the car-door in such position that it may be easilyopened and articles which may be in the car purloined. My invention isintended to obviate this objection by providing a car-door seal in whichthe sealing-pin and body portion are so constructed and arranged thatthe sealing-pin cannot be removed until the body portion has been takenfrom the car. The advantages of this kind of a construction are obvious,as it will be seen that the removing of the body portion cannot beeffected until the car is unlocked, and even then it cannot be effectedwithout considerable inconvenience.

In constructing my improvements I .make a body portion A, having twoprojecting lugs a a, provided with perforations a through which thesealing pin, as hereinafter described, is inserted. This body portion isprovided with two bolt-holes a a in line with the perforations ordirectly back of the sealing-pin, so that it renders it difficult forthe bolt in the perforation a to be reached at any time until thesealing-pin has been raised or opened.

A sealing-pin B is provided, which at its upper end is provided with eyeI), to which the usual chain may be secured, if desired, but which Ihave not illustrated, as I do not think it necessary to use the same,The lower portion of the pin is narrowed or flattened, as to 1) 72 sothat it may enter a narrow slot a in the upper lug of the body portionand its shoulder 12 act as a support to hold the pin in its up or openposition. This narrow portion of the sealing-pin is provided withextending wings or lugs b, which, as shown in Fig. 1, when the pin is inoperative position, limit the vertical movements of the pin. In otherwords, they prevent the pin from being removed as long as the bodyportion is secured to the car-door frame.

In order to insert the seal-pin in position, an enlarged opening A ismade in the back of the body portion, through which the wing portion ofthe pin may be inserted and permit the narrow portion 19 of the pin tobe passed through the narrow slot a until the pin assumes a verticalposition, when it may be dropped down through the perforation a It willthus be seen that unless the body portion is removed from its supportedpiece the pin cannot be taken out through this enlarged opening in theback of the body portion.

The lower portion of the sealing-pin is provided with two slots 19through which the ordinary seals may be passed for the purpose ofholding the seal-pin in a sealed and locked manner, as shown in Fig. 1.In this figure a hasp portion D is shown as secured to the door E on astaple land arranged to be passed over the lower lug a of the bodyportion, thus permitting the sealing-pin to be dropped down and sealed.

I olaim- 1. In seal-locks, the combination of a sealing-pin providedwith a sealing-perforation and projecting lugs for limiting its verticalmovements, a body portion having bolt-holes and lug portions providedwith perforations for receiving the sealing-pin, one of which extends toand through the rear portion through which the pin is removable only,substantially as described.

2. .In seal-locks, the combination of a sealing-pin provided with asealing-perforation and a narrow lower portion to form asupporting-shoulder, lugs on the narrow portion for limiting thevertical movements of the pin, and a body portion provided withbolt-holes and relatively lower and upper lugs having perforations toreceive the sealing-pin the perforation in the upper lug being irregularand extending to the back portion for the purpose of supporting the pinand allowing its withdrawal through the back portion only, substantiallyas described.

3. In seal-locks, the combination of a sealing-pin provided with asealing-perforation and a narrow lower portion to form asupporting-shoulder, two side projecting lugs on the narrow portion forlimiting the vertical movements of the pin, a body portion provided withrelatively upper and lower lugs having perforations to receive thesealing-pin the perforation in the upper lug having a narrow portion tohold the pin in an open position and extending through to an enlargedopening in the back portion through which the pin is removable only andbolt-holes in the body portion in line with the sealing-pin,substantially as described.
